People who can’t grow up and are short in stature may be caused by two diseases: thyroid hormone deficiency or growth hormone deficiency. 1. Thyroid hormone deficiency: clinically also called cretinism, due to hypothyroidism, caused by insufficient secretion of thyroxine, resulting in patients with obvious growth and development disorders, as thyroxine also promotes brain development, so not only will form a short stature, but also cause mental retardation, limb deformities, body shape ratio abnormalities. 2. Growth hormone deficiency, clinically known as dwarfism, is due to the lack of growth hormone, resulting in abnormal development of bone and cartilage tissues, resulting in short height and short limbs, but normal intellectual development. If growth retardation occurs, it should be diagnosed as early as possible and treated with exogenous hormone according to the diagnosis and medical advice.
